New research indicates that cancer survivors carry greater financial burdens related to medical debt payments and bills compared with individuals without a cancer history, with the greatest hardships in younger survivors. ...

Immune cells called macrophages are supposed to serve and protect, but cancer has found ways to put them to sleep. Now researchers at the Abramson Cancer Center of the University of Pennsylvania say they've identified how ...

Sechenov University researchers and German colleagues report a highly sensitive, painless method for diagnosing kidney cancer. This method is based on measuring of the immune response to arrestin-1, a retina protein that ...

The abnormal expression of different classes of molecules is known to be linked to various types of cells becoming cancerous. This is also true for the recently discovered group of small, noncoding molecules called microRNAs ...

Hope for treating the kind of brain cancer that took the life of U.S. Sen. John McCain lies with a compound, identified by researchers at UWM and the Medical College of Wisconsin, that slows the growth of this aggressive ...

An international team of researchers has identified a novel route that regulates the signaling pathways induced by extracellular matrix (ECM). This may serve as a new diagnostic marker and therapeutic target in the fight ...

The anxiety of being black, female and at the mercy of the U.S. healthcare system first hit Tina Sacks when her mother was diagnosed with breast cancer. Bette Parks Sacks, then in her 50s, intuitively knew something was wrong ...

Skin colour is one of the most visible and variable traits among humans and scientists have always been curious about how this variation evolved. Now, a study of diverse Latin American populations led by UCL geneticists has ...

The last 50 years has seen a rapid decline in male reproductive health. Decreased sperm counts, increased rates of testicular cancer and a range of malformations in male genitalia have been reported in industrialised countries ...

The search for a mechanism that could explain how the protein complex NCOR1/2 regulates memory has revealed an unexpected connection between the lateral hypothalamus and the hippocampus, the feeding and the memory centers ...

In the largest genetic study of osteoarthritis to date, scientists have uncovered 52 new genetic changes linked to the disease, which doubles the number of genetic regions associated with the disabling condition.

Children's heads expand steadily to accommodate their growing brains, and doctors routinely measure head circumference during the first years of life to assess healthy brain development. Children from around the world follow ...

Cancer /ˈkænsər/ ( listen), known medically as a malignant neoplasm, is a broad group of various diseases, all involving unregulated cell growth. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous. Benign tumors do not grow uncontrollably, do not invade neighboring tissues, and do not spread throughout the body.

Determining what causes cancer is complex. Many things are known to increase the risk of cancer, including tobacco use, certain infections, radiation, lack of physical activity, poor diet and obesity, and environmental pollutants. These can directly damage genes or combine with existing genetic faults within cells to cause the disease. Approximately five to ten percent of cancers are entirely hereditary.

Cancer can be detected in a number of ways, including the presence of certain signs and symptoms, screening tests, or medical imaging. Once a possible cancer is detected it is diagnosed by microscopic examination of a tissue sample. Cancer is usually treated with chemotherapy, radiation therapy and surgery. The chances of surviving the disease vary greatly by the type and location of the cancer and the extent of disease at the start of treatment. While cancer can affect people of all ages, and a few types of cancer are more common in children, the risk of developing cancer generally increases with age. In 2007, cancer caused about 13% of all human deaths worldwide (7.9 million). Rates are rising as more people live to an old age and as mass lifestyle changes occur in the developing world.
